FAUCET.

SPECIFICATION forming part of Letters Patent No. 265,457, dated October3, 1882.

Application filed August 14, 1882. (No model.)

To all whom tt may concern Be it known that I, JOSEPH G. STAPF, acitizen of the United States, residing at Pittsburg,

in the county of Allegheny and State of Pennsylvania, have invented anew and useful Improvement in that class of Faucets used for DrawingBeer, Ale, and similar Liquids; and my invention will be readilyunderstood from the following description, taken in connection with theaccompanying drawings, wherein- Figure l represents a side elevation ofmy improved faucet and air-pump attached thereto, a portion of thebarrel of the faucet being broken away to exhibit its interior where thebend of the air-pipe that leads through the tail of the faucet is madeto connect with the pump; Fig. 2, a'transverse vertical section of thefaucet-stem and lower portion of the pump and its means of attachmentthereto, together with the air-passa ges leadin gin that direction Fig.3, a ciosssection of the pump in a position to show the air-supplyingpassage and the arrangement of its valve.

The nature of my invention consists in a faucet having an air-pumpattached thereto, whereby air maybe forced through said faucet into avessel containing ale or beer in such a manner and in such quantities aswill insure a free discharge of the liquid without allowing any of itsnatural gas to escape.

lo this end I construct my faucet in any of the well-known forms and ot'any suitable material, but in order to accomplish the object of myinvention I prefer to construct my faucet so that on being driven into acask or other airtight vessel containing liquid the uid shall pass outof the nozzle c at the lower end of the key b, just back ot' which is ashort stout arm, c, that projects laterally a short distance and at aright angle to the barrel d of the faucet, and is integral therewith. Tothe outer end of this arm ois connected the base cot' the pump f bymeans of such a screw-coupling, g, as will allow the pump to be movedaroundiu a vertical plane without disengagingtheparts. This pump f isprovided'with a piston, h, supplied with suitable packing, and a rod,t', that extends upwardly through' a cap, j, screwed onto its top,terminating in a handle, It, by

which the piston may be actuated, the pump in this respect being verysimilar to others of a like character. Downwardly through the centralbase, c, of the pumpj'is a small hole, l, that leads into a cylindricalcavity, m, Fig. 3, one end of which is conical, and in this acone-shaped valve, n, is made to t, which valve is provided with a longstem, p, having its end supported in a tubular screw-cap, q, that servesto regulate the movement of the valve and tightly closes that end of thecavity. Frein this cavity m a horizontal passage-way, r, extends intothe projecting arm o of the faucetgthence by a sudden upward turn ashortdistance it connects with a small open-ended pipe, s, that is arrangedwithin the body d of the faucet, terminating at its tail end d after themanner and in the direction indicated by the dotted lines in Fig. l.Between the horizontal passage-way 1 and the pipe s, and a-t a point inthe upward turn of the passage-way, is located a small conical valve, t,the stem ot which enters so as to have free movement in a suitable hole,u, in a plug, o, that serves to close the opening through which thevalve was introduced. Above or around each of these valve-stems may beplaced a light spiral spring to hasten and insure a quick return 'of thevalves to their respective seats, and the several joints existingbetween any of the other parts may be provided with suitable packing.(lonnecting the pump to the faucet by means of a screw-coupling in themanner shown admits ot' its speedy and easy disengagement, so that itmay be readily removed for repair or other purposes, and left oft' .whennot required.

This contrivance having been constructed as shown and described, itsoperation is as follows: The tail end d of the faucet is to be driveninto an air-tight cask containing beer orotherliquid and the key bturned to such position as will permit the fluid to pass out, when, onmoving the piston of the pump upwardly, air will be taken in through theopening w, raising the valve n from its seat, and pass into the pumpunderneath the piston It. Areverse movement of the piston will force theair downwardly, its action being first to close that valve through whichit entered, and thus the entrapped air in combination with a detachableand adjustable pump connected thereto, land provided with a horizontalair-passage, r, and outlet-valve @internal pipe, s, operating inconjunction fvith the cylindrical space m Iind its inlet-vulve u to takein and force atmospheric air to the interior of a tight Cask or othervessel.
